The aim of this study was to gain knowledge of the pre-immune repertoire with reactivity directed to the carbohydrate antigen dextran B512 (Dx). Polyclonal activation of spleen cells in mice has been estimated to be a method of revealing the available repertoire. Hybridoma cell lines derived from lipopolysaccharide (LPS)-stimulated C57BL/6 spleen cells were screened for reactivity with Dx and with the non-related protein bovine serum albumin (BSA). Despite the lack of structural similarity… CONTINUE READING
